On the afternoon of the 12th, Xi Jinping, who was investigating and investigating in Shanxi, came to Taigang Stainless Steel Precision Strip Co., Ltd. The company was established in August 2008 and is located in Shanxi's comprehensive reform demonstration zone. Its main products are high-strength stainless steel precision strip with a thickness of 0.02 mm to 0.5 mm and a width of 3 mm to 650 mm.
Among them, the wide precision strip steel foil (thickness 0.02 mm, width 640 mm) was successfully developed in 2018 and became the world's first. Because its thickness is less than 1/3 of the diameter of the hair, it is thinner than A4 paper, and can be easily torn apart by hand. It is called "hand tearing steel".
△ Wide precision strip steel foil is called "hand-steel steel".
Previously, only a few countries could produce similar products, and the width was less than 400 mm. "Hand tearing steel" has extremely high added value of products, and is widely used in folding screen mobile phones, flexible display screens, energy storage batteries and other projects.
△ "Hand-Teared Steel" has high product added value. A piece of A4 paper-sized steel has a market price of about 400 yuan.
